Description

Lithium ion battery large-scale pole piece line banding machine
Technical field
The present invention relates to the large-scale polar sheat slicing machine of lithium ion battery;The processing method further relating to battery pole piece shaping.
Background technology
In the production process of electrodes of lithium-ion batteries, it is one of operation of non-the normally off key that pole piece shapes.Lithium-ion electric at present Pond pole piece shapes typically two kinds of technological processes, and one is directly to use die-cutting machine once-forming;Two is first to be completed with lug forming machine The lug of electrodes of lithium-ion batteries shapes, and then completes the shaping of overall pole piece by way of article points or shearing.But second Flow process is only applicable to small-sized pole piece, and the general length of pole piece after the electrodes of lithium-ion batteries that lug is cut after shaping shapes exists 100mm about;And the first flow process, die-cutting machine is once-forming to can guarantee that completing of large-scale pole piece, but in order to ensure shaping pole Complete, can there is 3-5mm gap, i.e. waste material between the pole piece being die cut out, certainly this can increase production cost, and the heaviest Want, single-piece molded is cut into making pole piece produce burr, and there is the technical problem of dry linting.Existing battery pole piece manufacturing process Usually cut first by little for disposable for entire volume pole piece shearing shaping polylith pole piece, less pole piece input brushing machine is coated with.This side Method is shaped by then passing through cutting die pressing, can produce burr at edge and the problem of dry linting easily occurs.Due to being once-forming, knife Mould size and pole piece consistent size, lead to not pole piece is carried out with secondary operations cause the pole piece that there is flaw can be directly entered electricity In the manufacture in pond, affect battery quality.
Content of the invention
The technical problem to be solved in the present invention is, solves monolithic die-cutting machine pole piece and shape there is asking of burr and dry linting Topic, and reduce the waste material in electrodes of lithium-ion batteries forming process, reduce production cost, a kind of electrodes of lithium-ion batteries is provided Shape banding machine.It is another object of the present invention to improving the processing method that battery pole piece shapes.
The technical scheme is that lithium ion battery large-scale pole piece line banding machine, be provided with including above frame, frame Positioning panel, positioning panel both sides are provided with positioning power cylinder, the push plate of positioning pole piece, have absorption to fix in front of positioning panel The absorbent module of pole piece, forms clamping plate type positioning, is provided with pusher motor, rear is provided with slitting mill on front side of positioning panel to pole piece Head, rolling cut rear part of head is provided with discharge roller, and frame is provided with Electric machine with gear-box, and pusher motor and discharge roller form plug-type feeding, Battery pole piece shapes for rolling cut.
Further, the chopper external diameter in rolling cut head 4 is φ 71.5mm;Discharge roller adjustable-height;Positioning panel The positioning power cylinder of both sides setting coordinates the pole piece accurate positioning after push plate guarantee full wafer cross cutting;The power of rolling cut head with Charging transmission, the power of discharging transmission separate independent.
Described clamping plate type positioning is provided with horizontal moving cylinder.
Clamping plate type positioning, plug-type feeding, be centrosymmetric between rolling cut article points distribution;Pull feed, rolling cut article points Work surface is in same level;Pressing plate is had to prevent pole piece from warping in pole piece positioning push pedal;Before and after pole piece enters cutting operation All there is absorbent module to provide tension force;It is designed with anti-coiled strip assembly in pole piece cutting.
This line banding machine can connect a brushing machine or be simultaneously connected with two brushing machines it is also possible to connect the special dress that takes up Put.
Monoblock pole piece is first divided the conveying of left and right both sides to send into article points through moving sheet devices by the processing method that battery pole piece shapes Machine, through rolling cut head 4, pole piece is longitudinally spaced apart, then enter brushing machine through discharge roller 6.
The present invention has the positive effect that: this banding machine is due to being positioned using clamping plate type, plug-type feeding, pole piece inhale Attached, rolling cut article points mode, have pole piece be integrally die cut, pole piece positioning, pole piece cutting function.It is no longer single when pole piece is integrally die cut Only a piece of but whole piece, between pole piece, waste material very close to each other produces it is most important that the process that shapes pole piece is by shearing Shaping is changed into rolling cut and shapes, it is to avoid the problem of pole piece grain raising and dry linting.Simultaneously because being directly die cut as full wafer, no longer mould It is cut to monolithic, improve the work efficiency of cross cutting.
Electrodes of lithium-ion batteries is configured to article points after overall cross cutting, it is to avoid the generation of gap waste material, improves material profit With rate, reduce production cost., using 650 taking more conventional anode pole piece (l13078660-400) 123x452mm as a example Die-cutting machine, single is die cut 5, and the waste material of generation substantially can be divided into three parts, the edge waste material of both sides, the waste material of lug both sides Waste material and between pole piece;And the waste material two parts using the present invention to produce, save waste material between pole piece, area is { 4x [5x (452+47)]=9980mm2, only account for the 3.3% of total spreading area.
Electrodes of lithium-ion batteries is integrally die cut back edge and all cuts off, and during article points, pole piece does not have tension force easily to occur Wrinkle, offset, even split scarce phenomenon, therefore reduce the incidence rate of these defects in article points using hobboing cutter handpiece structure, exist simultaneously It is designed with adsorbing mechanism before and after at article points to position and tensioning pole piece.
The present invention is a single entirety, has good versatility, client's itself production status visual decide whether by This equipment puts into whole production line.This equipment whether there is the operation conditions that can't affect whole production line.
